Detection of volcanic unrest onset in La Palma, Canary Islands, evolution and implications

Abstract La Palma island is one of the highest potential risks in the volcanic archipelago of the Canaries and therefore it is important to carry out an in-depth study to define its state of unrest. This has been accomplished through the use of satellite radar observations and an original state-of-t...
